TRAVELER FOR TWISTER RINGS.

Application filed December 1, 1922. Serial No. 604,409.

To all witam it may concem:

Be it known that I, GEORGE H. GILLIGAN, a citizen of the. United States, residing at N ew Bedford, in the county ofl Bristol and State of Massachusetts, have invented certain new and useful Improvements in Travelers for Twister Rings, of which the followin is a specification.

y invention relates to ring travelers for use upon the rings of twisters or twist-img frames in distinction from spring rings; and particularly to the Vertical type of traveler. An essential object of my invention is to prevent the tilting or cramping of the ring whereby the thread is subjected to excessive tension which develops weakness and destroys the fiexibility of the thread.

A further object is, by mainta-ining the traveler in an upright position, to-prevent Wearing, lcutting, or grooving the traveler, and to prevent excessive heating of the ring, whereby the lub-ricant is so speedily dried as to require exoessive and frequent lubrication of the ring. Another object is to maintain the thread remote from the greasy face of the ring.

Other objects are to increase the speed and durability of the traVeler. To the above ends essentially my invention consists in such parts and in such combinations of parts as fall within the scope of the appended claims.

In the accompanying drawings which form a part of this specification, Figure 1 is a perspective View of a twister ring showing my novel ring traveler in op- .erating position thereon, w

Figure 2, a fragmentary similar View of the ring showing the traveler in another operative position,

Figure 3, a section on line 3 3Vof F igure 2, and F igure 4, an enlarged perspective view of the traveler.

Like reference characters indicate like parts throughout the views.

As shown, 7 is the Vertical t-wister ring in the rail 8 of a twister frame; and 9 is my traveler mounted thereon.

This t-raveler is cut and formed from a thin metallic blank, and comprises a Vertical shank ll, rovided in this instance with an inward concavity 12 intermediate its length. Integral with the upper end of the shank is a'head or lip 13 comprising a horizontal portion 14 and a terminal downwardly inclined portion 15. Centrally of the port-ion 14 is a hole 16 from which extends a slot 17 to the outer extremity of the portion 15, thus bifurcating the latter. F lormed upon the B0 lower end of the shank is .a foot or lip 19 comprising in this instance a substantially horizontal portion 20 and a terminal upturned portion 21.

The thread, filament., yarn, strand or other -material 23 extends from the rolls downwardly through the hole 16, and thence laterally beneath one half of the lip portion 14 to the spool or bob'bin. Access to the hole is afl'orded the thread through the bifurcation 17.

It will be observed that. the use of the hole enables the traveler to move in its circular path without laterally or otherwise tilting or twisting the shank. Hence grooving, excessive heating, or other disadvantages resultant upon frictional contact of the traveler with the ring are avoided, and the thread 23 is maintained remote from the face of the ring 7.

' I claim 1. A traveler for Vertical twister rings comprising a Vertical shank, a lip integral with the lower end of the shank, and a. lip integral with the upper end of the shank provided with a hole, and with a guide slot extending from the last mentioned lip. i

2. A traveler for Vertical twister I'ings comprising a sha-nk, a lip integral with the lower end of the shank, and a lip intearal with the upper end of the shank provided with' a longitudinally disposed opening extending from an intermediate portion of said hole to the' edge of the lip to the edge thereof.

In testimony whereof I have aflixed my signature. v
